Summary
Vacaville Municipal Code Section 14.09.250.060 protects all trees with a diameter at breast height of six inches or more. Significant pruning that risks destroying the tree requires authorization from the Director of Community Development. Routine maintenance trimming is allowed, but cuts that exceed standard arboricultural practice can trigger a Tree Removal Permit requirement and replacement-tree mitigation.
(2) Remove that portion of a tree that extends within 10 feet of the outlet of a chimney or stovepipe. (3) Maintain a tree, shrub, or other plant adjacent to or overhanging a building free of dead or dying wood. (4) Maintain the roof of a structure free of leaves, needles, or other vegetative materials. ... (B) A greater distance than that required under subparagraph (A) may be required by state law, local ordinance, rule, or regulation. Fuel modification beyond the property line may only be required by state law, local ordinance, rule, or regulation in order to maintain 100 feet of defensible space from a structure. Fuel modification on adjacent property shall only be conducted following written consent by the adjacent landowner.
Full Breakdown
060 prohibits removing OR destroying any tree on public or private property with a diameter at breast height (DBH) of six inches or more without authorization. The ordinance covers severe pruning where the cuts are so extensive that the tree's health, structure, or canopy is permanently compromised - this is treated the same as removal. Routine ANSI A300-style maintenance pruning (deadwood, crown cleaning, structural pruning, hazard reduction within 25% of canopy) is generally allowed without a permit. Topping a mature tree, removing more than 25% of the live canopy, or cutting back trees to stubs typically triggers Tree Removal Permit review by the Director of Community Development, and the City may require a replacement tree.
Street trees and trees in the public right-of-way are managed by the Public Works Department; residents should coordinate with Public Works before pruning any tree in the parkway strip. Trees on private property near power lines may be trimmed by PG&E under California PUC General Order 95 right-of-way clearance standards. The Community Development Department processes Tree Removal Permits with a 21-day minimum turnaround.
Violations & Fines
Severe pruning or topping of a protected tree (DBH 6 inches or more) without authorization is treated as removal and subjects the owner to enforcement under VMC 14.09.250.060, including replacement-tree requirements, restoration orders, and administrative citation. Public-tree damage is separately enforceable through Public Works.
